PROBLEM TO BE SOLVED: To provide an imaging method which is hardly affected by B0 ununiformity or B1 ununiformity, and can acquire a high quality image.SOLUTION: An MR device comprises scan means. Te scan means executes a sequence including a composite pulse A including an αpulse and βpulse, a composite pulse B including a βpulse, 2αpulse and βpulse, and a composite pulse C including a βpulse and αpulse. The θ, φ, θ, and φare expressed by θ=θ+λ, φ=φ+λ, θ=θ+λ, φ=φ+λ, in which λ=λ+90°×m, and λ=2λ+90°×m.SELECTED DRAWING: Figure 8 |
